Application mea December 2o, l1923. serial No. 681,684.

To aZZ whom it may concer/n Be it hereby known that we, CHARLES Z. EDELsON, JACOB GOLDEEN, and MILTON D.

TARLOW, citizens of the' United States, and

residents of Portland, in the county of Multnomah and State of Oregon, have in vented a new and useful Mattress, of which the following .is a specification.

an exceedingly simple and efficient mattress which will neither sag nor stretch.

A further object is to so construct the mattress that there will be a movement of air within the mattress whenever any of its portions are compressed or released.;

A still further Object is the utilization of air within thenmattress as an insulating medium which will make the mattress warm` in cold weatherand cool in warm weather, owing to the fact that the air filler can absorb and retain only a small amount of heat.

Another object is the utilization of springs having initial tension which are confined within each biscuit of the mattress between a pair of convex covers, which covers are then connected by spacing means.

Still another object is the centering of the springs in the various biscuits, and to make it possible to employ roll edge and tufting machines now in common use in the art.

In addition to these objects we have endeavored to maintain the -utmost flexi-A bility and resiliency in the mattress, and at the same time make same reversible.

We accomplish these results in the manner set forth in the following specification and illustrated in the accompanying drawings in which:-

Figure'l is aplan of the mattress of which Figure 2 is'an end elevation and Figure 3 a section along the line 3--3 in -Figure f 1. Figure 4 is a plan of four units assembled. Figure 5 is a section along the line 5 5 in Figure 4 with the chains omitted. Figure 6 is a front elevation of one of the spring units. enlarged section through a convex cover',

showing the manner in which the chainsl are attached to the-cover and spring. Figure 8 is a slight modification of Figure 7 in which the edge of the cover is shown curled around the sprin' Similar numbers of re erence refer to the Figure 7 is anv *i same parts through out the several viewsi In its preferred form our invention conslsts of a horlzontal outer ring 10 having `formed in its periphery a plurality of eyes 11. Above and below each ring 10 is placed the opposing convex covers 12 having vthe downturned edges 13. Holes 14 are provided in the cover 12 which correspond with the eyes 11. A spiral spring 15 is compressed between the covers 12, -and the chains 16 are employed to unite the covers 12 to the ring 10.

Ring clamps 17 pass throu h thev eyes 11 I of the adjacent rings 10 an flexibly 'join the palrs of rings 10. It is preferable to pass the links 16AA of the chain 16 around.

the coil 15A of thespring 15, as well as around the edge 13 of the cover 12, as this attaches the cover 12 to the spring 15 and also reduces" the strain on the cover itself.

Leather thongs or cords 16B could, of course, be employed in place 'of the chains 1 6 without departing from the spirit of our invention. 1

`When as many unitsof the device have beenA assembled as there are to be biscuits 18 in a complete mattress, they are covered on each side by a sheet of light cloth 19 and a layer of illmg 20, which may be any of s the substances used in the artfor this purpose, such as loose or felted cottony silk' ioss, hair, feathers, etc. stood that i/f certain of these fillers are used that it would be more practicable to introduce same in a separate ticking, or to first insert the spring units and covers 19 and then inject the Eller, as is commonly done, the function of the sheets 19 being merely to prevent the filler from getting between the springs. v

It will be under-g v falls, so to speak, in the well formed by the' ring 10. The units around the one on which the pressure is applied are not disturbed. No stretching or distorting of any kind -results. After continuous use any springwill weaken and be less able to return to its This is especially true original positionwhen no initial tension is supplied. It is this'initial tension which provides the reserve of strength for the spring and insures each biscuit 1'8 being returned to its proper position as soon as its load is removed.

The covers 12, as stated, are placed in the center of each biscuit 18 and they remain there at all times since they are confined to the center of the ring 10 by the chains 16, and the rings 10 are definitely located with relation to the entire mattress by the clamp 17.

`Without the chains 16, or their equivalent, the covers 12 would be free to expand as far as they were able to stretch the material and to move around in the biscuit 18. Without the covers 12 the springs 15 would soon break through the mattress filler and ticking. The chains 16, of course, support their portion of the cloth 19.

In the prior artmany instances may be found in which the ends of the springs of mattresses are stayed from one to the other, which, of course, causes lateral movement of the area surrounding that which carries the load, and the ultimate sagging and stretching of the mattress.

While we have illustrated the device as located in the middle of a mattress, it is evident that the same device can easily be employed in other forms of upholstery, or even as a bed spring itself, by merely providing a support for the lower covers 12.

Owing to the hingelike connection betwe'en the various rings 10 itis easily seen that the mattress can be folded in either direction along its length or breadth. The matstress, too, isr'eversible, which is a quality often sacrificed when springs are incorporated therein.

Owing to the fact that the various spring units are joined, it is evident that the mattress which surrounds same must retain its rectangular shape. Slnce saggmg 1s eliminated, the top and bottom tickmg 1s not 'drawn inwardly, which ordinarily makes it `10 as bemg made of sheet material instead of being formed out of round Wire,- which construction might be preferable in some cases Where extreme lightness is desired in the construct-ion, aluminum may be used for the metal parts, except the springs.

We are aware that springs havelong been employed in mattresses and upholstery in many dlerent ways, we therefore intend to cover only such forms and modifications as fall fairly `within the appended claims.

We claim: u

D' 1. A spring unit for mattresses consistmg of a ring; a. spring placed in the center of said ring; a cover placed over each end' of said spring; and flexible means for attaching said covers to said ring, adapted to assist in supporting said mattress. 2. A spring unit for mattresses consistmg 'of a` ring; a spiral spring placed in the center of said ring; a convex cover secured over each end of said spring; and a plurality of chains joining said v cover to said ring in a manner that initial tension is present in said-spring when said' covers are separated as far as possible, and to support their portion of the mattress.

3. The combination of a plurality of spring units consisting of rings hinged at their pointsA of tangency; a spiral spring placed within each ring; a cover on each end of each spring; and chains joining each cover to its respective spring in a manner that said spring can be compressed without changing the relation of the remaining units. i

4. A mattress having, in combination, an external tick; a layer of filling against the upper and lower sides of said tick; a plurality of spring units placed between said layers of filling, each of said units comprising an outer ring hinged on its sides to its adjacent rings; a spring placed in said ring Iunder compression; a cover over each end of said spring; means for flexibly securing said covers to said ring in a manner to limit the expansion of said spring; andy tufts passing through said mattress between sets of four spring units.

5. In a mattress, the combination of a plurality ofvcircular spring units spaced to register with the biscuits of a mattress, said units being hinged at their points of lll) tangcncy to adjacent units, each of said units comprising an outer Wire ring; a spiral spring Within said ring; a convex cover on each end of said ring; means for attaching said cover centrally to said ring in a manner to compress said' spring; a cloth casing around said units; a filler around said casing; a tick around said iiller; and

tufts located in the intersections between any four spring units, each of said spring units operating to expand the material inside of any four adjacent tufts in a manner to form a biscuit.
